Way back when this game was released I was a freshman in college. Naturally all of the guys I lived with played video games a lot, and because we didn't all have Live accounts we essentially shared accounts. So, my roommate played this game on my Live account... a lot.

Anyway, I bought the game a week ago to grab some achievements (and because I found it for $9.99). I got online and found that my account has all of the unlockables associated with an elite ranking and it appears to have an elite ranking when I look at my outfitting screen, BUT I don't have any of the achievements associated with leveling up. Does anybody know what could have caused this/how to fix it?
